P ICKER-STICK CHECK FOR LOOMS.

SPECIFICATION forming part of Letters Patent N 0. 729,229, dated May 26,1903.

Application filed November 28,1902. Serial No. 133,027. (No model.)

To aZZ whom, it may concern.-

Beit known that I, GEORGE M. SMITH, a citi zen of the United States,residing at Berkeley, in the county of Providence and State of 5 RhodeIsland, have invented a new and useful Improvement in Picker-StickChecks for Looms, of which the following is a specification. 7 '7 V Thisinvention has reference to looms, and

I more particularly to the picker-sticks of looms.

The object of this invention is to prevent any rebounding and chatteringof the pickersticks when they have reached their outward I limit underthe impulse of the floor-springs and to hold the picker-sticks underspring tension in their proper position to throw the shuttle from theshuttle-boXes.

This invention consists in the peculiar and novel construction of aspring-check attached to the under side of the shuttle-boxes, having twoflat bent springs, forming a clip for receiving, checking, and holdingthe pickersticks under spring tension, as will be more fully set forthhereinafter and pointed out in the claims.

Figure l is a front view of a loom, showing my improved picker-stickchecks attached to the under side of the shuttle-boxes, with thepicker-sticks held in the spring-clips of the checks. Fig. 2 is anenlarged front view of my improved picker-stick checks, showing part ofa picker-stick in its inward position in full lines and held in thecheck in its outward 3 5 position in broken lines. Fig. 3 is a plan viewlooking at the under side of my improved picker-stick check, showing thetwo flat bent springs forming a wedge-shaped clip for receiving,checking, and holding the pickerstick in the check under spring tension.

In the drawings, a a are the shuttle-boxes of aloom. The picker-sticks aa are operated in the usual way by the picking-cones and picker-strapsto throw a shuttle from the shut- 4 5 tle-boxes. The floor-springs a aare secured to the floor at one end and to the lower end of thepicker-sticks by a strap or other means returning the picker-sticks totheir outward or normal position after the throw of the shuttle by thepicker-sticks To check and hold the picker-sticks in their outward ornormal position under spring tension, I attach or secure my improvedspring-check to the under side of the shuttle-boXes by the plate Z) andthe screws 1) b. The plate I) has the opening b forming a stop for thepicker-stick, and the two downwardly-extendin g bosses b b placed at aslight angle to each other and forming two sides of the opening 11 Thetwo flat springs b b are secured at their fixed ends I) Z) by the screws17 b to the outside of the bosses 11 12 The springs b are carriedoutward from their support 011 the bosses for a predetermined distance,flaring away from each other, and are then bent inward and backward,bringing the free ends Z) I) in the opening 12 forming a wedge-shapedopening between the springs for the picker-stick, as shown in Fig. 3.

In the operation of my improved picker- 7o stick check the shuttle isthrown in the usual way by the picker-stick. from the shuttle-box. Thepicker-stick now returns to its outward or normal position by the actionof the floor spring on itslower end. This forces the upper end of thepicker-stick into the mouth of the wedge-shaped opening between the fiatsprings b b and against the inner faces of the free ends I) b, when thepicker-stick comes to arest on the stop 5 formed by the opening b in theplate I), forcing the free ends I) b apart and checking and holding thepickerstick under springtension until released by the action. of thepicker-cones through the picker-stick strap to throw a shuttle from the8 5 shuttle-box.

As a new article of manufacture my improved picker-stick check is veryinexpensive to make and simple in construction, comprising practicallythree parts, and the springs, by their shape, are not easily brokenunder the action of the picker-stick.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a picker-stick check, a plate having an opening toreceive and form a stop for the picker-stick, two projecting bosses 011the plate, means for securing the plate to a shut tle-box, and two flatsprings secured to the X00 bosses at their fixed ends andcarried out- Intestimony whereof I have signed my Ward for a predetermined distance,then inname to this specification in the presence of ward and backward,bringing their free ends 'two subscribing Witnesses.

and hold the picker-stick under spring ten- B. S. WVEBSTER,
